I took a pretty rough spill skiing a few years ago that screwed up my left shoulder and thumb. Physio helped a lot, but I still have nagging pain when I move stuff the wrong way.
Holding down that thumb stud is one of those wrong ways. It starts as a dull ache, but escalates pretty quickly. After a few rounds of loading & shooting 4 mags, the thumb pain's radiating to my wrist and I start to lose wrist strength. Whatever I'm subconsciously doing with my left arm to compensate for that makes my shoulder start to hurt too, and once that starts my range day is pretty much done.
I solved the problem on Saturday.
